Dust can cause significant damage to electronic products. For example, when the headphone jack or data port of your phone gets filled with dust, it can affect functionality. Precision instruments are typically manufactured in cleanrooms, where lint-free cloth is commonly used. As a versatile cleaning cloth for cleanrooms, what special advantages does it offer?

1. The primary advantage of lint-free cloth is its excellent dust removal capability.
Polyester microfiber lint-free cloth and polyester/nylon composite microfiber cloth, with their unique fiber-splitting process, can remove more micro-dust and dirt in both dry and wet conditions.

2. It also has strong liquid absorption capacity.
It can absorb various liquids and resist corrosion from various acidic and alkaline chemical reagents.

3. Lint-free cloth produced in professional-grade cleanrooms also offers advantages such as low ion leaching, ultra-low particle generation, and ultra-low residue.

4. Lint-free cloth will not damage products.
Some lint-free cloths not only clean products effectively but also have soft, non-damaging properties, making them popular among cleanroom manufacturers.

5. Lint-free cloth can be reused multiple times.
In lower-grade cleanrooms, lint-free cloth can be reused after proper cleaning, though it must be washed before each reuse.

How to test lint-free cloth and lint-free paper? For most of us, the difference between lint-free cloth and lint-free paper may seem superficial — one is cloth and the other is paper. But how do you test them separately? Let’s learn about the testing methods.

Lint-Free Cloth Testing Methods:
1. The quality of lint-free cloth depends on its thickness and weight. Heavier weight means thicker cloth. Choose different weights for different product cleaning needs.
2. Pull the cloth from both sides, then hold it at an angle toward a light source and examine with a magnifying glass for broken fibers. Broken fibers appear as lint on the surface. The fewer broken fibers, the better the quality.
3. Wipe a fingerprint or smudge off your touchscreen phone with the cloth to see if it can be removed in one pass.
4. Dip in alcohol and wipe your phone screen or glasses to check for residue or lint.
5. In a cleanroom, shake the cloth under light to see if excessive debris falls off.

Lint-Free Paper Testing Methods:
1. Check the surface for paper dust. Rub it in your hands to see how much lint comes off.
2. Feel the hardness and thickness by hand.

These simple testing methods are for emergency situations when no instruments are available. Professional testing requires specialized equipment.

ESD Dust Removal Sticks are specially designed for highly clean environments (Class 10-100). The raw materials are highly clean, non-linting, with low ion content and free from allergens. They feature excellent chemical corrosion resistance, and the anti-static treatment safely dissipates charges without being affected by environmental changes. Suitable for cleaning in the manufacturing and assembly of static-sensitive products.

I. Uses of ESD Dust Removal Stick:
With excellent adsorption properties, it is mainly used to remove micro-dust particles from the exposed coated SENSOR surface in the COB process. Compared with ordinary cotton swabs (using cleaning water to wipe the CSP SENSOR surface glass), it does not generate dust spots, will not scratch the SENSOR, leaves no stains, and can significantly improve product yield.

Removes PARTICLES from LED/LCD surfaces in Class 10-5000 cleanrooms.

Cleans debris and particles from LENS surface glass.

II. Characteristics of ESD Dust Removal Stick:
1. Made with specially formulated adhesive, permanent tackiness, non-volatile, no stringing.
2. Soft, flexible, with good maneuverability and operational feel.
3. Environmentally friendly, no irritating odor, harmless to users.
4. Provides excellent protection for product electrical properties and appearance.

ESD Dust Removal Sticks are specially designed for highly clean environments (Class 10-100). The raw materials are highly clean, non-linting, with low ion content and free from allergens. They feature excellent chemical corrosion resistance, and the anti-static treatment safely dissipates charges without being easily affected by environmental changes. Suitable for cleaning in the manufacturing and assembly of static-sensitive products.

ESD Dust Removal Stick Operating Instructions:
1. Remove the outer packaging, clean the outer packaging, pass through the air shower, then enter the cleanroom.
2. Before operation, prepare the 5S: workbench, floor, equipment, chairs, gloves, tools, fixtures, trays, etc., and inspect with a microscope.
3. Gently pick up the stick with tweezers from the tray. Do not let the adhesive end touch any objects to avoid contamination. Hold the other end by hand.
4. Align the adhesive stick with the dust spot under a microscope or software, maintain a 60°~90° angle, and gently dab. Do not apply excessive force to avoid scratching or damaging the SENSOR.
5. Hold steadily during use. Do not shake back and forth or rub against the product to avoid scratches.
6. Each stick should be used no more than 15-20 times per product to avoid secondary contamination.
7. Keep used sticks away from the work area and separate them from clean sticks.

Storage Precautions:
1. Store flat side up. Do not place on its side or upside down.
2. Store away from light.
3. Storage temperature below 30°C.
4. Shelf life: two years.
